RAILWAY TRACK-DRILL.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed September 9, 1905. Serial No. 2'77|'7Q6.

To all whom, it may concern:

Be it known that I, EUGENE CooK, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Railway Track- Drills, of which the following is a specification.

.This invention relates to improvements in railway track-drills.

The main object of this invention is to provide an improved railway track-drill which may be readily collapsed for transportation or storage or to allow a train to pass.

Another object is to provide a structure possessing the above advantages which is, when set up or erected, very strong and rigid.

A further object is to provide in a railway track-drill an improved feed device.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined, and point ed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of a structure embodying the features of my invention. Fig. 2 is a rear elevation thereof looking from the right of Fig. 1. Fig. 3 is an enlarged detail vertical section taken on a line corresponding to line 3 3 of Fig. 4. Fig. 4 is an enlarged detail horizontal section taken on a line corresponding to line 4 4 of Figs. 1 and 3. Fig. 5 is an enlarged detail section taken on a line corresponding to line 5 5 of Fig. 8, showing the bearing and the connection of the gear G. to the drill-holder. Fig. 6 is an enlarged detail sectional view taken on a line corresponding to line 6 6 of Fig. 3, showing details of the feed device. Fig. 7 is a sideelevation view of my improved track drill in a folded or collapsed position. Fig. 8 is a detail vertical section takenon a line corresponding to line 8 8 of Fig. 7, showing structural details of the rail-engaging hooks and their supports. Fig. 9 is a detail vertical section taken on a line corresponding to line 9 9 of Fig. 7. Fig. 10 is a detail showing structural details of the supportingbars D for the hooks. Fig. 11 is a detail showing a modification of the rest of the brace when in its extended position.

In the drawings, the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, A is the main frame, which is preferably rectangular in form and disposed in a horizontal position. The frame A preferably consists of suitable parallelarranged side pieces, with crosspieces connecting the same.

A standard B is pivoted on the uprights A at the forward end of the frame by the bolts b. The standard B serves as a support for the shaft J of the cranks which is arranged transversely in suitable bearings at the upper end, and the tool-holder driving-shaft G, which is arranged in suitable bearings in the cross-pieces of the standard. The drivingshaft G is connected to the shaft J by beveled gears J J. The upper cross-piece B of the standard B forms a handle for manipulating it in collapsing or erecting. The standard B is locked in its upright position by the brace C, which is pivoted thereto at its upper end. WVhen the brace C is in its extended position, its lower end, which is provided with feet 0, engages suitable rests on the main frame, (see Figs. 1 and 2,) or the brace may rest upon the rail-engaging hooks, as is illustrated in the modified construction of Fig. 11. The brace C is locked in its extended position by the jointed arms I, which are pivoted thereto toward its lower end and to the uprights A of the main frame preferably by the pivot-bolts b of the standard B. The jointed arms I are preferably of the well-known carriage-top-- brace construction. These arms automatically lock when they are forced downwardly, but may be readily released by lifting upwardly until their pivots are carried pass the deadcenter.

On the rear end of the frame A is a trans versely-arranged base A, upon which the operators may stand to assist in steadying the machine when in operation. This is also of advantage, as it forms a broader base for the frame, so that it will rest upon more than one tie when adjused to drill a rail.

In use the machine is held in position by hooks D, which engage over the rail, as

engaged by the lower end of the brace C when it is forced rearwardly, thereby draw-- ing the hooks into position against the rail as the brace is locked in its extended position. It is evident that the hooks are also looked when the brace is extended. The hookshanks D are preferably shaped somewhat like I-beams to secure strength and lightness. The hooks are retained in the ways by the lugs L, (see Fig. 9,) which project into the inner channel Z of the shanks. The lower flanges of the hooks are notched at Z, so that they may be inserted in the ways, the notches receiving the lugs or stops L. This arrangement allows a slight rocking movement of the hooks in the ways, so that the hooks may be lifted sufliciently to clear the top of the rail in adjusting. The rear ends of the hooks are also provided with stops (1, which limit their forward movement, thereby preventing their Withdrawal from the guides.

In setting up the drill for operation the standard B is elevated and the hooks D are engaged over the rails. The brace C is then extended, which movement draws the hooks tight against the rails, in which position they are locked, as described. WVhen it is desired to collapse the structure, the brace O is released, which frees the hooks so that they may be slipped forwardly and lifted over the rail. They are then free to slide backwardly to the position indicated in Fig. 7, and the standard B may be folded on the frame, as

therein indicated.

To limit the rearward movement of the hooks, a stop or lug d is provided. This stop is adapted to engage a suitable projection, as n, on the uprights A. Shoulders d are formed on the under sides of the hooks in such a position that they drop over the projecting end of the crosspiece a of the main frame when the lug d is in its engaging position. This looks the hooks so that they will not slip in either direction 'unless lifted upwardly to release the stops d from the crossbar. A handle D, which serves as a connecting means for the hooks, is provided for convenience in their manipulation. If desired, the rail-engaging hooks may be slightly modified to engage under the rail instead of over it, as I have illustrated herein.

The tool-holder E is horizontally arranged in a suitable bearing, as a, on the main frame. Splined to the tool-holder by a suit able feather, as e, is a forwardly-facing beveled gear G arranged so that the gear G on the lower end of the drivingshaft G is brought into mesh therewith when the standard B is in its upright or erected position. The gear G is mounted in suitable bearings a. The hub of the gear G is provided with an annular groove g in the bearing portion thereof, which serves to secure the gear in position, preventing the lateral movement thereof, the babbitt, as g, of the bearing being cast about the same filling the groove .and locking the gear in its bearing. (See Fig. 3.)

The tool-holder is fed forwardly by the screw F and the internally-threaded ratchet F thereon. The screw F is hollow to receive the rear end of the holder, which is secured thereto by means of the set-screw f, which engages an annular groove 6 in the toolholder. An end bearing F is provided for the tool-holder F. This preferably consists of a threaded bolt or pin tapped into the end of the screw F, as is illustrated. The screw F is supported in suitable bearings ct, arranged at each side of the ratchet-wheel, so that they also serve to prevent the lateral movement of the ratchet-wheel. To prevent the revolution of the screw, it is mutilated or flattened on one side (see Fig. 6) to receive the key-blocks f, which are arranged in the bearings 0/. the rotation of the screw, so that when the ratchet-wheel is operated the screw is moved backward and forward. The ratchet-wheel is operated by means of the pivoted lever H, having a pawl H at one end and a camengaging fork H at the other end. This lever is pivotally mounted on the bracket H by means of the pin h. The bracket H and the lever H are provided with two or more bearing perforations for the pivot-pin it, so that It is evident that this prevents 9 5 the throw of the lever can be regulated, and

thereby the feed of the tool-holder controlled.

The lever is operated by the cam G on the shaft G, the forked end H of the lever engaging the cam when the standard is in its upright position. It is evident that this forking of the lever allows the cam to swing out of engagement with it when the frame is collapsed or folded. At the same time it readily receives the cam when the frame is erected.

By arranging the parts of my improved track-drill as I have illustrated and described I secure a structure which may be readily set up or erected to begin work or may be quickly knocked down to allow a train to pass or for the purpose of transportation or storage, and one which, when in the knockdown, is very compact. The structure is also very simple and convenient to use and when set up or erected is very rigid.

While I have described my invention as a 'track drill, it is evident that a wrench or other tool may be used instead of'a drill.

I have illustrated and described my improved railway track drill in detail in the form preferred by me on account of its struc- I tural simplicity, economy, and convenience in use. I am aware, however, that it is capable of considerable variation in structural details without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
